Polymer emulsions are milky-white liquids consisting of polymers dispersed in water. The main applications of polymer emulsions include paints, coatings, adhesives, and sealants. The expansion of the construction and automotive industries in Europe has resulted in the growth of the aforementioned application segments, and thus is estimated to drive the growth of the European polymer emulsions market during the forecast period of 2013-2018.

When we come across special purpose application such as H2SO4 dilution plant acid cooling, chromium bath cooling, Chlorinator cooling etc. Then major problem is due to corrosion and its effects due to fouling and scaling. In this research work, new polymer coated materials are developed and tested for its thermal and mechanical properties. We have develop plate type heat exchanger with this developed material Polly vinyl based polymer coating on the mild steel plates. This heat exchanger is...

This work reports the ionic conductivity of polymer films of tapioca / 1,4,polyphenylene ether ether sulfone(PPES), with lithium based salt and multiwall carbon nanotubes (MWCNT) as fillers which were prepared by solvent casting technique. The ionic conductivity of the films is studied at room temperature using ac impedance spectroscopic technique. X-ray diffraction (XRD), FTIR and SEM studies have been made to investigate the structural, complexation and variation in film morphology of the...

Most of the pharmaceuticals are administered by the popular route of drug delivery, the oralroute. Taste is an important and critical parameter in administering formulations which comesin contact with the taste buds. Many drugs have bitter taste, thus this is one of the importantformulation problem encountered. Bitter taste of drugs has posed a constant problem in thetreatment of patients due to their inability or unwillingness to swallow such formulationespecially in children and elderly. Thus... Topics: Taste masking, dosage form, palatability, and polymer.
In this work, we conducted a study on the extraction of natural polymer and use of natural polymer such as coagulating agent in the process of coagulation/flocculation for water treatment, which was carried out to study the removal of turbidity parameter. The natural polymer was extracted from the plant Moringa oleifera, and the extraction occurred in saline, and saline solutions were employed, so did the monovalent (KCl and NaCl) and divalent (BaCl2, CaCl2 and MgCl2). Therefore, given that the... Topics: Polymer Natural Moringa Oleifera, Coagulation/Flocculation

The polymer – ceramic composites have superior characteristics and play vital role in various applications. In the present study, a polymer – ceramic composite is developed using the high molecular weight PMMA and zirconium titanate. While the former is prepared by the polymerization of MMA , the latter is prepared by sol gel method. The composite samples are characterized using DSC,PXRD, and SEM. The high Tg values of polymer composite show the restricted segmental motions of the polymer... Topics: Polymer composite, PMMA, Zirconium titanate, corrosion resistance.
Acrylonitrile Butadiene Styrene (ABS) has several mechanical applications such as gears, bearings, washers etc. In these applications, wear is the primary cause of failure. In this study ABS from e-waste was reinforced with short glass fibers (SGFs). The effects of SGF concentration, on the mechanical properties of the composites were examined. Increasing the SGF concentration at a weight ratio of 5 and, 30% resulted in improved tensile strength, tensile modulus, but drastically lowered the...

This paper studies the behavior of simply supported steel I-beams strengthened with carbon fiber reinforced polymers (CFRP) strips on the web as shear reinforcement. The experimental program contains seven simply supported steel beams. One of them was considered as a control beam and the other specimens were strengthened with different schemes; varying the position of CFRP strips to the web, its number of layers and its angle of orientation. The results show that applying CFRP strips on the web... Topics: carbon fiber reinforced polymer, steel, specimen, strengthening.

Poly aniline (PANI) separately blended with polyvinyl alcohol (PVA) and Polyethylene oxide (PEO) has been prepared by solution cast method using N-Methyl Pyrrolidone (NMP) as common solvent. The structural changes of PANI-PVA and PANI-PEO films were studied by XRD and FTIR techniques. XRD and FTIR studies confirmed the complex formation in polymer blends. The change in the intensities in the polymer blend and appearance of new peaks in the FTIR spectra revealed the blending of poly aniline with... Topics: Poly aniline, Polymer blend, Dc conductivity
The surface of an acrylate-based shape memory polymer ("SMP") was modified to capture cationic biomarkers of eosinophilic esophagitis ("EoE") to establish a better diagnostic and monitoring system of this disease. Incorporation of a negative charge into the SMP allows for specific adsorption of the cationic biomarkers with additional leverage from the shape memory effect to position the polymer near the lumen wall of the esophagus. SMP modification was performed by... Topics: biomedical engineering, acrylate-based shape memory polymer

Research progress of weak alkaline and non-alkaline compound flooding technology was reviewed. The weak alkaline flooding system, which replaced strong alkali (NaOH) with inorganic weak alkaline (Na2CO3, NaHCO3), buffer alkaline (Na2CO3/NaHCO3) and organic weak alkaline (weak polymer acid sodium salt),could obtain the same recovery ratio with alkaline-surfactant-polymer flooding. The betaine combinational flooding of polymer/ampholytic surfactant and hydrophobically associating water-soluble...
